Arthur 0. La Ducer, Hartford, Conn., assignor to The Wiremold Company,Hartford, Conn., a corporation of Connecticut Application December 24,1935, Serial No. 55,956

7 Claims.

My invention relates to lighting systems, and

. comprises a type of reflector and means for mechanically supportingthe same and for connecting it to the electrical circuit. It isparticularly useful in connection with electric lamps such as thoseknown as Lumiline, or other lamps de signed to produce the effect oflines of light, referred to hereinafter as line lamps.

In the drawing,

Fig. 1 is a general view of my improved lighting means;

Fig. 2 is an elevation, partly in section, on the line 22 of Fig. 3;

Fig. 3 is an elevation cross section on the line 33 of Fi 2;

Fig. 4 is a similar section on the line 4-4 of Fig. 2;

Fig. 5 is similar to Fig. 4, but shows the refiector set at a differentangle, and also shows an alternative type of fastening'mean's for therefiector;

Figs. 6 and 7 show the lamp receptacle and th means for attaching it inplace.

The member l0, Figs. 1, 3, 4 and 5, is a section of conduit/here shownas of the well-known type known to the trade as Wiremold?; suitable forenclosing and protecting such electrical conductors as are used in housewiring, which may be secured to a wall, floor, ceiling, etc. in anysuitable way, as by screws ll, Fig. 1, This conduit is normally coveredor closed in, as by a cover strip i2, Figs. 1 and 4.

At suitable points, this cover strip is interrupted, and is replaced byone of the receptacle members l3 shown in Figs. 6 and '7, which memberis so shaped as to serve as a cover for the conduit, and is fastened inplace by the lugs 14, ll, which bear on the inner side or the upper edgeof the conduit, as shown in Figs. 1 and 2, and which are held in placebythe screws i5, I5.

Each receptacle is provided with two slots, l8, l3, each of whichcontains a pair of spring contacts ll, if, all four contacts of thereceptacle being, in the arrangement shown, integral with a metal platel8 which is held in a recess H in the bottom of the receptacle by aninsulating 25, 25, shown as of the well-known Lumiline type, in whichthe filament 26 extends longitudinally along the center of the lamptube, and is connected at each end toa terminal plug or contact (notshown) which enters one of the recep- 5 tacle slots l6. In this way I amable to support on and connect to the conduit ID a line of lamps,mounted end to end, so as to afford a practically continuous andunbroken line of light.

The reflectors 21, 21, are herein described as part-cylindrical, bywhich I mean that each refiector is in the shape ofa fraction, asillustrated about half, of the surface of a figure which is either atrue cylinder or departs from true cylinder shape so far as is necessaryto control the distribution of the reflected light in the desiredmanner. Each of the reflectors is mounted on or attached to the conduitto by some suitable fastening means; for example by either the clip 28of Fig. 4 or the screw 29 of Fig. 5. The clip 28, which embraces theprojecting portion 30 of the conduit cover- 42 is fastened to thereflector 21 by the screw 30; the screw 29 of Fig. 4 enters into thetapped central opening of the stud 3|, which is riveted to the covermember i2.

-In either case the screw, whether 29 or 30, passes through a hole inthe reflector. A part of the means for mounting the reflector at any oneof a plurality of angular positions, which is highly desirable, as, itpermits a single standard reflector model to be used to produce a.plurality 'of different light distributions, and in each position toprovide a maximum of reflecting surface, is the provision of a set oftwist-outs 32, 32, which do not substantially interrupt the reflectingsurface, but any one of which may readily be punched out to afford anopening for the screw 29 or 30. As part of the same means, I provide ateach end of each reflector a second series of twist-outs 33, 33, anyadjacent two of which may be removed to afford an opening in the end ofthe reflector adapted to embrace a portion, preferably one half, of theprojecting part 34 01' the receptacle l3, asshown at 34 in Fig. 2, so asto allow the two reflectors which meet at any particular receptacle tocome directly together: end to end, to avoid any substantial loss ofreflecting surface at that point, and at the same time to aiford roomfor the receptacle 34 and for the contacting and supporting membersdiepending from the lamp.

' The locations of the twist-outs 33, 33, at one end of the deflectorare so related to those 01' the twist-outs 33, 33, at the other'end andto the location of the twist-outs u that at any position in which thereflector may be mounted; that is to say, with any one of the twist-outs32 punched out to aflord an opening for the screw 29 or screw all; thereare two adjacent twist-outs 33, that each end of the reflector which, ifremoved, will embrace and afford room for a suitable portion of theprojecting part 3d of the receptacle l3.

Kile projecting members 34 are suitably curved to fit the circular caps35 on the ends of the lamps, to afford better mechanical support for thelamp.

I thus provide means for supporting cheaply,

rigidly and efiiciently a lineof lamps of any desired length, end toend,and means to feed current to the same, and also support a continuousline of reflectors, arranged end to end, having their axes parallel tothe axes of the lamps, and capable of being mounted at any one of aplurality of angular positions in order to bring about variousdistributions of light.

I claim:

. l. The combination of a plurality of line lamps arranged in line witheach other, sockets for said lamps, a series of elongated reflectormembers of curved cross-section arranged in line with each other andwith their longitudinal axes parallel to the axes of the lamps, the endsof said reflector members having a series of twist-outs removable toaccommodate said lamp sockets with the reflector members mounted in anyone of a plurality of angular positions, and means for holding thereflectors'in place with their ends in substantial contact at any one ofa plurality of angular positions.

'2. In combination, a conduit, wires therein, line lamps, a series oflamp sockets attached to the conduit adapted to electrically connect theline lamps to wires in the conduit and to mechanically support the linelamps in line with each other and withthe conduit,a series of elongatedreflectors of curved cross-section each provided with a series oftwist-outs for permitting the reflector to be' fastened in any one of aplurality of angular positions and with a corresponding series oftwist-outs at each end to accommodate the lamp sockets when thereflectors are assembled in line with each other and with the lamps.

3. In combination a conduit, lampsockets supported by the conduit, linelamps supported by the sockets in line with each other and with theiraxes substantially parallel to the axis of the conduit, elongatedreflectors of curved cross-section and means for holding .the reflectorsin place with their longitudinal axes substantially parallel to the axisofthe conduit, said holding means being aoeaoao capable of holding thereflectors in any one of a plurality of angular positions, and a seriesof series of twist-outs at each end spaced angularly around thelongitudinal axis of the reflector, each twist-out being capable ofproviding an opening for a socket, and an intermediate series ofcorrespondingly spaced twist-outs to facilitate the fastening of thereflector in position.

5. An elongated reflector of curved cross-section having at'each end aseries oftwist-outs, the twist-outs at opposite ends beingcorrespondingly spaced about the longitudinal axis of the reflector andarranged to provide openings indifferent positions through which a lampsocket may beinserted, and also having a series of correspondinglyspaced provisions for fastening means for holding the reflector inplace.

6. An elongated reflector of curved cross-sec 'tion having at each end aseries of twist-outs, the

twist-outs at opposite ends being correspondingly spaced about thelongitudinal axis of the reflector and arranged to provide openings indifferent positions through which a lamp socket may be inserted, andalso having an intermediate series ofcorrespondingly spaced twist-outsadapted to afiord openings for supporting the reflector.

'7. In combination a series of fittings connected by sections ofconduit, wires therein, line lamps, a series of lamp sockets attached tothe fittings and adapted to electrically connect the line lamps to wiresin the fittings, a series of elongated reflectors of curvedcross-section each provided with a series of twist-outs spaced angularlyabout the longitudinal axis of the reflector for permitting thereflector to be fastened in any one of a plurality of angular positionsand with a series of correspondingly spaced twist-outs at each endadapted to accommodate the lamp sockets when the reflectors areassembledin line with each other and with the lamps.
